[0025] First of all, referring to FIGS. 2 through 6, the shoe forwalking and skating in accordance with the present invention includes ashoe 1, a locating plate 2, two locating members 3 a, 3 b, two rollers 4and a brake 5.

[0026] The shoe 1 has a sole 11 provided with a front and a rear holdinggrooves 12, 13.

[0027] The bottom of the locating plate 2 includes a front and a rearlocating frames 21, 22 respectively corresponding to the front and rearholding grooves 12, 13.

[0028] The locating members 3 a, 3 b are respectively fixed in the frontand the rear locating frames 21, 22 by means of screws 23. Each of thelocating members 3 a, 3 b has a button 31 at either side thereof forpushing a pivoting element 32 to control the axial movement of alocating pin 33 while a cap 34 is used to fix the button 31, thepivoting element 32 and the locating pin 33. Besides, a compressionspring 35 is interposed between the cap 34 and the locating pin 33,thereby creating a resilient force required by the locating pin 33 inreturning to its original position. Moreover, a mounting bar 36 with anelongated groove 361 is movable ups and downs and mounted on either sideof the locating members 3 a, 3 b.

[0029] The rollers 4 are mounted on the elongated grooves 361 of themounting bars 36 by means of screws 41. In addition, an upper and alower locating holes 42, 43 are disposed at both sides thereof so thatthe locating pin 33 can be inserted into either of the upper and a lowerlocating holes 42, 43 for fixing the rollers 4 in place.

[0030] The brake 5 has a locating housing 51, a locating rod assembly 52and a braking piece 53. The locating housing 51 together with the rearlocating member 3 b is arranged in the rear locating frame 22. Thebraking piece 53 outwardly projects or is hidden inside by means of thelocating rod assembly 52 together with an upper and a lower fixing hole531, 532.

[0031] The sole 11 is provided with a plurality of through holes 14 atpositions corresponding to each of the buttons 31 and the locating rodassembly 52.

[0032] In addition, the braking piece 53 serving as a contact body 533with the ground is made of a high-abrasive plastic material.

[0033] Moreover, a compression spring 37, 54 is respectively arranged inthe locating members 3 a, 3 b and the locating housing 51 of the brake5.

[0034] Furthermore, the locating rod assembly 52 is composed of a sleeve521, a spring 522 and a fixing pin 523. The spring 522 fitted to theinside of the sleeve 521 supports against the fixing pin 523. And adomed head 524 is mounted on the outer end of the fixing pin 523 forpulling.

[0035] Referring to FIG. 4, the rollers 4 and the braking piece 53 arelocated for a skating mode. At this time, the rollers 4 are directeddownwardly and the braking piece 53 projected outwardly. With referenceto FIGS. 5 and 6, the rollers 4 are located by means that the locatingpin 33 is inserted into the upper locating hole 42 while the brakingpiece 53 is located by means that the fixing pin 523 of the locating rodassembly 52 is inserted through the upper fixing hole 531. As shown inFIG. 7, in changing the locating mode of the rollers 4 and the brakingpiece 53, the button 31 is pressed down to retract the locating pin 33by means of the pivoting element 32, thereby creating a releasing state.Meanwhile, the fixing pin 523 of the locating rod assembly 52 is pulledoutwardly to release the braking piece 53.

[0036] Thereafter, as shown in FIGS. 8 and 9, when the rollers 4 isreleased, they will fall down along the elongated groove 361 of themounting bar 36 (while the mounting bar 36 also falls down) so that therollers 4, as shown in FIGS. 10 and 11, have the revolving space. Afterthe rollers 4 are revolved, as shown in FIG. 12, the locating pin 33restores itself by means of the resilient force of the spring 35 in alocked state. Meanwhile, the locating pin 33 is inserted into the lowerlocating hole 43 to hide the rollers 4 in place. Besides, the fixing pin523 of the braking piece 53 also restores itself by means of theresilient force of the spring 522 in a locked state. Meanwhile, thefixing pin 523 is inserted into the lower fixing hole 532 to hide thebraking piece 53 in place, as shown in FIGS. 13 and 14. Accordingly, awalking function is created. To the contrary, the rollers 4 and thebraking piece 53 can be changed from the hidden state to the exposedstate. The method thereof is similar so that it won't be described morehereinafter.

[0037] As shown in FIGS. 15 and 16, another embodiment of the locatingrod assembly 52′ is formed as a press switch, and the fixing pin 523′ istelescopic to located the braking piece 53 in place. Meanwhile, thearrangement position of the braking piece 53 is fixable and adjustableas well.

[0038] Accordingly, no matter for performing the skating or the walkingfunctions, the front and rear holding grooves 12, 13 of the sole 11 aresealed by the top rim of the rollers 4, thereby preventing the foreignbodies from entering into the front and rear holding grooves 12, 13 sothat the cleanness in the front and rear holding grooves 12, 13 isensured. In addition, it is avoidable that the rollers 4 are blocked byimpurities, causing malfunctions. Moreover, the braking piece 53 isarranged for securing the safety in use. Moreover, it is only requiredto press the button 31 to push the pivoting element 32 for an axialmovement of the locating pin 33, thereby releasing the locating pin 33from the upper or the lower locating holes 42, 43. Thereafter, therollers 4 is revolving to change the arrangement position. At the sametime, the position of the braking piece 53 can also be adjusted by thelocating rod assembly 52. Again, when the rollers 4 and the brakingpiece 53 are received in the holding grooves 12, 13 and the locatinghousing 51, they can be taken out smoothly by the compressed spring 37,54 without the conventional blocking problems. Therefore, it's veryconvenient to change the locating direction of both rollers 4 while thelocating position of the braking piece 53 can also be changed by thelocating rod assembly 52 so that the present invention is convenient inuse.

[0039] Many changes and modifications in the above-described embodimentsof the invention can, of course, be carried out without departing fromthe scope thereof. Accordingly, to promote the progress in science andthe useful arts, the invention is disclosed and is intended to belimited only by the scope of the appended claims.
